τμ = 2.1969803(2.2) × 10−6 s MuLan 2011 ⇒ GF = 1.1663787(6) × 10−5 GeV−2 so precise that error in atomic mass unit (u) can shift GF (MuLan quotes GF = 1.1663788(7) × 10−5 GeV−2) finite MW in the W-propagator no longer negligible: correct for, i.e., absorb in Δq: τμ−1 ~ GF2 (1+ Δq)

  • r not, i.e., absorb in Δr: √32 GF ≡ g2∕MW2 (1+ Δr)

latter convention motivated by effective Fermi theory point

When combined with the absence of BSM signals at the LHC ⇒ more and more likely that new physics is separted from the SM by at least a little hierarchy. Only tantalizing deviation is in gμ−2.
